The Nip Tuck season finale, which has been promoted as a 2 hour show on Tuesday, 12/20, originally showed up as 2 1-hour episodes on my ToDo list. In the last day or so, they were combined into 1 entry for Tuesday. Note: FX shows, especially season premieres and finales tend to run over--be sure to pad this one by at least 5 minutes. During the season, you may only miss the preview for the following week, but on the final show, they incorporate that time into the show.
The one nasty effect of this change is that subsequent showings still show up as 2 episodes, distinct from the Tuesday night show, and thus, make it to the To Do list.
